Rumors that Lavigne was sick spread after a fan account started tweeting out hashtags "#PrayForAvril" and "#GetWellSoonAvril." The pop star may have fueled the rumors a bit by tweeting back: "Thank you."

The fan account also shared direct messages that were allegedly from Lavigne. "I feel bad because I haven't been able to say anything to the fans to let them no why I've been absent," the alleged private tweets read. "I'm torn as I'm quite private…I'm not feeling well. I'm having some health issues. So please keep me in your prayers."
